4-perf
Negative pulldown is the manner in which an image is exposed on a film stock, described in the number of film perforations spanned by an individual frame. It can also describe the orientation of the image on the negative, whether it is captured horizontally or vertically. Changing the number of exposed perforations allows a cinematographer to change both the aspect ratio of the image and the size of the area on the film stock that the image occupies (which affects image clarity). The most common negative pulldowns for 35 mm film are 4-perf and 3-perf, the latter of which is usually used in conjunction with Super 35. 2-perf, used in Techniscope in the 1960s, is enjoying a slight resurgence due to the birth of digital intermediate techniques eliminating the need for optical lab work. Vertical pulldown is overwhelmingly the dominant axis of motion in cinematography, although horizontal pulldown is used in IMAX, VistaVision (still in use for some visual effects work), and in 3 ...

35 Mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard image exposure length on 35 mm for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film stock supplied by George Eastman. F ...

Techniscope
Techniscope or 2-perf is a 35 mm motion picture camera film format introduced by Technicolor Italia in 1960. The Techniscope format uses a two film-perforation negative pulldown per frame, instead of the standard four-perforation frame usually exposed in 35 mm film photography. Techniscope's 2.33:1 aspect ratio is easily enlarged to the 2.39:1 widescreen ratio, because it uses half the amount of 35 mm film stock ''and'' standard spherical lenses. Thus, Techniscope release prints are made by anamorphosizing and enlarging each frame by a factor of two. Techniscope-photographed films During its primary reign of 1960–1980, more than 350 films were photographed in Techniscope, the first of which was ''The Pharaoh's Woman'', released 10 December 1960. Given its considerable savings in production cost but lower image quality, Techniscope was primarily an alternative format used for the production of lower-budgeted film, mainly those in the horror and western genre ...

Anamorphic
Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen (not to be confused with anamorphic widescreen, a different video encoding concept that uses similar principles but different means). The word ''anamorphic'' and its derivatives stem from the Greek ''anamorphoun'' ("to transform"), compound of ''morphé'' ("form, shape") with the prefix ''aná'' ("back, against"). In the late 1990s and 2000s, anamorphic lost popularity in comparison to "flat" (or "spherical") formats such as Super 35 with the advent of digital intermediates; however, in the years since digital cinema cameras and projectors have become commonplace, anamorphic has experienced a considerable resurgence of popularit ...

VistaVision
VistaVision is a higher resolution, widescreen variant of the 35 mm motion picture film format which was created by engineers at Paramount Pictures in 1954. Paramount never used anamorphic processes such as 2.55: 1, CinemaScope but refined the quality of its flat widescreen system by orienting the 35 mm negative horizontally in the camera gate and shooting onto a big area, which yielded the finer-grained projection print. As finer-grained film stocks appeared on the market, VistaVision became obsolete. Paramount dropped the format just after seven years, although for 40 more years the format was used by some European and Japanese producers for movies, and by USA movies such as the first three ''Star Wars'' films for high-resolution special effects sequences. In many ways, VistaVision became the testing ground for every cinematography idea that evolved into 70 mm IMAX and OMNIMAX film formats in the 1970s. Both IMAX and OMNIMAX are oriented sideways, like Vist ...

Super 35
Super 35 (originally known as Superscope 235) is a motion picture film format that uses exactly the same film stock as standard 35 mm film, but puts a larger image frame on that stock by using the space normally reserved for the optical analog sound track. History Super 35 was revived from a similar Superscope variant known as Superscope 235, which was originally developed by the Tushinsky Brothers (who founded Superscope Inc. in 1954) for RKO in 1954. The first film to be shot in Superscope was '' Vera Cruz'', a western film produced by Hecht-Lancaster Productions and distributed through United Artists. When cameraman Joe Dunton was preparing to shoot ''Dance Craze'' in 1982, he chose to revive the Superscope format by using a full silent-standard gate and slightly optically recentering the lens port (to adjust for the inclusion of the area of the optic soundtrack -the gray track on left side of the illustration). These two characteristics are central to the format. It ...

Arricam
Arricam is a 35 mm movie camera line manufactured by Arri. Description It is Arri's flagship sync-sound camera line, replacing the Arriflex 535 line. The design was developed by Fritz Gabriel Bauer and Walter Trauninger, and is heavily derivative of the cameras Bauer created for his Moviecam company, which was bought out by Arri in the mid-1990s. As such, the Arricam is a fusion of the mechanical and intuitive design innovations of the Moviecam and the interchangeable accessories and complex electronic integration of the Arriflex. {{As of, 2006, the Arricam is considered, along with the Panaflex Millennium line, the top sync-sound camera system currently in usage, and is extremely popular amongst bigger budget feature films. The line comprises two camera body models, the ST (Studio) and LT (Lite). The Arricam ST is intended as a full-capability camera, including two camera magazine mounting configurations, whereas the Arricam LT is optimized for smaller, lightweight usage in ...

Aspect Ratio (image)
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as ''16:9'', sixteen-to-nine. For the ''x'':''y'' aspect ratio, the image is ''x'' units wide and ''y'' units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography. Some common examples The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1.The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the American Society of Cinematographers' ''American Cinematographer Manual'' (Many widescreen films before the 1970 SMPTE revision used 2.35:1). Two common videographic aspect ratios are 4:3 (1.:1), the universal video format of the 20th century, and 16:9 (1.:1), universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently. In still camera photography, the most common aspect ra ...

Aaton
Aaton Digital (formerly known as Aaton) is a French motion picture equipment manufacturer, based in Grenoble, France. History Aaton was founded by Eclair engineer Jean-Pierre Beauviala, whose efforts have been primarily focused on making quiet, portable motion picture hardware suitable for impromptu field use, such as for documentaries. A model for all motion picture cameras they have produced is the "cat-on-the-shoulder", a small, light, quiet motion picture camera. In the late 60's Beauviala was working as a professor of electronics in the University of Grenoble. With the project to make a movie about the evolution of the city and of its architecture, but unable to find the proper tools, Beauviala decided to create the camera himself. Though the movie would eventually be abandoned this led to the creation of Aaton in 1971. After several initial prototypes, the Aaton LTR 16 mm movie camera became available on the market in the late 1970s. It has been succeeded by several imp ...

Technicolor
Technicolor is a series of Color motion picture film, color motion picture processes, the first version dating back to 1916, and followed by improved versions over several decades. Definitive Technicolor movies using three black and white films running through a special camera (3-strip Technicolor or Process 4) started in the early 1930s and continued through to the mid-1950s when the 3-strip camera was replaced by a standard camera loaded with single strip 'monopack' color negative film. Technicolor Laboratories were still able to produce Technicolor prints by creating three black and white matrices from the Eastmancolor negative (Process 5). Process 4 was the second major color process, after Britain's Kinemacolor (used between 1908 and 1914), and the most widely used color process in Cinema of the United States, Hollywood during the Golden Age of Hollywood. Technicolor's #Process 4: Development and introduction, three-color process became known and celebrated for its highly s ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Aperture Mask
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the ray cone angle and brightness at the image point. In some contexts, especially in photography and astronomy, ''aperture'' refers to the diameter of the aperture stop rather than the physical stop or the opening itself. For example, in a telescope, the aperture ...
